Last week I got a question about deploying Hyper-V hosts via MDT Lite touch, so here is a quick guide. In this example I'm assuming you have imported an operating system to the Deployment Workbench. In my example I was using a Windows Server 2019 image.
1. Create a task sequence and select the Standard Server Task Sequence Template in the wizard, and also select the imported Windows Server 2019 operating system. See the below screenshots:
2. Edit the new task sequence, add the Install Roles and Features option, select Windows Server 2019 in the dropdown list, and then select Hyper-V in the list.
